Otto Karl Fröhlich

Otto Karl Fröhlich , often OK Fröhlich , (* May 6, 1885 in Jägerndorf , Silesia , † January 20, 1964 in Vienna ) was an Austrian civil engineer for geotechnical engineering and university professor .

Fröhlich studied civil engineering at the Graz University of Technology , where he acquired the degree of graduate engineer in 1909 and received his doctorate in 1911 . He then worked as a civil engineer in Berlin , Saint Petersburg and, after military service in the First World War, from 1920 to 1927 in Amsterdam , from 1927 to 1929 in London and from 1934 in The Hague (as a consulting engineer for foundation engineering). This also resulted in collaboration with Karl von Terzaghi , whom he represented from 1935 to 1937 in his professorship at the Vienna University of Technology . This is where the book about consolidating clay layers with Terzaghi was written in 1936 . After Terzaghi went abroad in 1938, mainly because of the political situation in Austria after the “Anschluss” , Fröhlich became his successor and, from 1940, full professor for foundation engineering and soil mechanics and director of the earthworks laboratory at the Vienna University of Technology. He was succeeded in 1957 by Hubert Borowicka , who was a student of Terzaghi in Vienna.

In addition to work on ground pressure under foundations and consolidation, he also developed a theory of slope stability .
